Equipment Manual, 08/2020, A5E48753535-AA
Diagnostics: Wire break
Enabling of the diagnostics if the analog input module has no current flow or the current is
too weak for measurement at the correspondingly configured input.
Note
Wire break diagnostics
With analog input channels, wire break diagnostics is not possible for the measurement type
voltage ± 80 mV.
The following table shows the diagnostics that may occur on wire break.

Diagnostics: Overflow/Underflow (for PROFIBUS only)
Enabling of the diagnostics when the measured value exceeds the overrange or falls below
the underrange.
Diagnostics: Underflow
Enabling of the diagnostics when the measured value falls below the underrange.
Diagnostics: Overflow
Enabling of the diagnostics when the measured value exceeds the overrange.
Conductor resistance
Parameters for the measurement types resistor and thermal resistor (2-wire connection).
The parameter is used to compensate the conductor resistance without interfering with the
sensor wiring.
